That is an unusual NPK value you got there - not sure what your goals are with your trees but this seems to be a very aggressive growth mix :-)

Anyone else have something to add?

I think cut and paste got things out of order. I think Nitrogen belongs with ammonium nitrate.

It looks like 20% nitrogen, 15% phosphorus or potassium and real low for the other. Maybe a photograph?

Yep, little high on nitrogen, but it's ok, since it's osmocote, it's quite safe to use.
